Modifed scheme of high-voltage buck DC-DC converter for electric locomotive

This paper shows a modified scheme of a high-voltage buck DC-DC converter. The main characteristics are shown, described operation of a scheme: the external characteristics, the regulation one, the dependence on the harmonics of the input current and the output voltage of the duty cycle. Moreover, it has defined the total power losses and the coefficient of efficiency in this scheme. The comparative analysis is made with characteristics of the two-module converter.
